The relevant file libavcodec/h263dsp.o gets compiled 
here because config.mak defines H263DSP here with 
your configure line and this forces libavcodec/Makfile 
to enable compilation of libavcodec/h263dsp.o:

$ make distclean
$ git pull
$ configure --disable-encoders --disable-decoders --disable-yasm \
--enable-shared --disable-static
$ grep H263DSP config.mak
$ make ffmpeg
$ ls libavcodec/h263dsp.o
